    case was one of fibroid pneumonia. The anatomical dis- closures clearly show that this was a case of chronic broncho-pneumonia (as is evident from the thickened septa and alveolar walls); that towards the termination of the disease, parts of the lung broke down, and circumscribed areas surrounding such ulcerations had become the seat of a fibrinous exudation which underwent fibroid metamor- phosis. The lobular condensations in the lower lobe are most probably to be regarded as produced by the insuffla- tion of the sanious contents of the cavities. This case I have given in some detail to emphasise the fact already adverted to, in treating of the secondary variety of fibroid pneumonia, that limited secondary indurations of the lung are not at all uncommon, and are apt to mislead, if the history of the case, the naked eye features and general morbid anatomy of the affected lung be overlooked. A lung, the seat of bronchiectasis and cavities—possibly gangrenous—and presenting lobular and partially diffuse consolidation, is not to be regarded as an example of fibroid pneumonia. In nine cases out of ten such, the consolidation is secondary, and when diffuse, results from the confluence of several lobular patches. The follow- ing case illustrates this:—A man, aged 59, from whom no history was obtainable, was admitted to the hospital in a state of great exhaustion, with a temperature of 102-2', very oppressed breathing and profuse purulent and very offensive expectoration. He died shortly after admission. Post mortem, both lungs were consolidated throughout the greater part of their extent. The consolidation was lobular, but at intervals was diffuse. It had generally a remarkable appearance, like a number of tubercular consolidations. Two gangrenous cavities communicating with dilated bronchi were found in the base of the left lung, while the right had a cavity in the apex and
